Jason Lowe updated YARN-364:
----------------------------

Patch to add a config so the log retention check interval can be specified.  
Defaults to one-tenth of the aggregated log retention time.

> AggregatedLogDeletionService uses the yarn.log-aggregation.retain-seconds 
> property to determine which logs should be deleted, but it uses the same 
> value to determine how often to check for old logs.  This means logs could 
> actually linger up to twice as long as configured.
